4 Claims.

This invention relates to goosenecks for containers, and its principal object is to provide a gooseneck which may be easily and thoroughly cleaned, and in the event that any of its restricted passageways or ducts become clogged, they may be readily cleared of the obstruction.

The main difiiculty which has been heretofore encountered in goosenecks in which the several parts are integrally united, is the difficulty of clearing the passageways and ducts of matter which clogs them. Usually this requires the services of an expert, and when the gooseneck becomes clogged, it is sent to a service station for cleaning.

One of the objects of this invention is to provide a gooseneck in which any obstructionin any of the restricted passageways or ducts may be easily cleared by unskilled persons.

Another object is to provide a gooseneck for containers and composed of separable parts which may be readily disconnected for the purpose of cleaning them and clearing the passageways and ducts of any matter that clogs them.

Another object is to provide a gooseneck of this character for use on containers such as bottles,

jars and the like, and arranged to be connected to an air line and a fluid conducting line for conducting fluids (liquids) to and from the container under the influence of minus or plus pres-' sure, which is supplied to the container through the air line by a vacuum pump or a pressure pump, as the case may be.

With these and other objects and advantages in view, this invention consists in the several novel features of construction, arrangement and combination of parts hereinafter fully set forth and claimed.

The invention is clearly illustrated in the drawing accompanying this specification in which;

Fig. 1 is a central vertical section through a container, partly broken away, and equipped with a gooseneck embodying a simple form of the present invention;

Fig. 2 is a detail central vertical section of the gooseneck alone;

Fig. 3 is a detail horizontal section taken on the line 33 of Fig.2;

Fig. 4 is a plan of a certain sleeve member forming partof the device; and

Fig. 5 is a side elevation, partly broken away, of a slightly modified form of a tubular member which comprises part of the device.

Referring to said drawing, and first to Figs. 1 to 4, inclusive, the reference character 6 designates a container such as a bottle ar or the like, here shown in the form of a glass bottle having a neck 1. The gooseneck, designated generally by the reference character 8, is supported in an opening in the container and the joint between the gooseneck and container is hermetically sealed to prevent air from leaking into or out of the container. When a bottle is used, a rubber stopple 9 is employed between the gooseneck and neck of the bottle.

In the form of the invention illustrated, the gooseneck comprises a tubular member I0, and a sleeve member I l, surrounding the tubular member and having a threaded connection therewith whereby the two may be readily connected and disconnected. The tubular member is somewhat longer than the sleeve member and each end is provided with a tapered enlargement 12, whereby flexible tubes l3, l4 may be attached to the tubular member. The flexible tube 13 leads to a suitable container, surgical instrument, or other object or place, from which liquid is to be drawn into the container on which the gooseneck is used, or to which it is to be conducted from said 0011'- tainer. The flexible tube [4 leads from the lower end of the tubular member H] to a point adjacent the bottom of the container 6.

The sleeve member H is formed at its upper end with a head l5, from the lower side of which depends a sleeve it, which is of a slightly greater internal diameter than the external diameter of the tube portion ll of the tubular member ID, to provide an annular air passageway l8 between the sleeve IB and tube l1.

The annular air passageway is open at its 'low- -er end and terminates at its upper end within the head l5, and leading from said passageway within the head is a duct or port [9, which in accordance with the form of the invention illustrated extends at right angles to the axis of the tube and opens out through the side face of the head. A threaded nipple 20, having the usual tapered enlarged end for attachment to a flexible tube 2|, is threadedly secured in the head in open communication with the duct or port I9. The flexible tube 2| is connected to a sourceo vacuum supply or air pressure. The head I5 is provided with internal .scre

threads 22 in the bore of its upper portion and the tubular member. II is formed with a reduced externally screw-threaded neck 23 that is screwed into the screw-threaded bore of the head. The upper face of the head may be provided with a depression 24 to receive a gasket or washer 25 for making a leak-proof joint between the tubular member and sleeve member. Both of said members have knurled faces, whereby they may be firmly grasped when assembling or separating the two members of the device.

In the modified form illustrated in Fig. 5, the upper end of the tubular member I is provided with a tube Ill which is bent upon itself into a somewhat U-shape and provided upon its extremity with the usual tapered enlargement l0 whereby a flexible tube may be connected to it. In other respects the construction of the device is substantially the same as that of the preferred form.

In the operation of the gooseneck, the flexible tube 2| is connected to a pump, either a pressure pump or vacuum pump, as the case may be. When the device is used to convey liquid from the container to some remote place, a pressure pump is employed and the pressure within the container is raised sufficiently to force the liquid out or it. The air from the pump enters the duct or port l9 through the nipple 20 and passes down through the annular passageway l8 and into the container, thereby forcing the liquid up through the flexible tube I4, the tubular member ID, and flexible tube l3, to the place where it is to be delivered.

When used to convey liquid to the container, a vacuum pump is connected to the flexible tube 2| and a partial vacuum is created in the container, the flexible tube [4, tubular member 20, and flexible tube 13, thereby causing the liquid to flow from its source to the container.

In devices of this character, solids are likely to gather in the restricted passageways and ducts,

thus obstructing the flow of air. Whenever an obstruction occurs in the present device, the tubular member and sleeve member may be readily separated from each other and a wire or other slender object may be thrust through the hole in the nipple 20 and through the duct or port I9, thereby dislodging any obstruction therein. Furthermore, with the parts separated, all surfaces thereof may be readily and quickly cleaned.

More or less variation of the exact details of construction is possible without departing from the spirit of this invention; I desire, therefore, not to limit myself to the exact form of the construction shown and described, but intend, in the following claims to point out all of the invention disclosed herein.
